A new study out of the University of Pittsburgh found that men depend on alcohol to have a good time hanging out, but women don’t. The main reason is because guys are too embarrassed to show emotions, even happiness.  However, after a couple brews, men smile more, they’re less inhibited, and feel closer to their friends. On the other hand, women don’t rely on alcohol to show emotions, so they can have fun and bond without it. (Photo: Wanderlust)
